Wi h th s 'o j in V w, g h i h will presently appear. It will, of course, be 5 others. which Will appear as the description understood that the howing of the flying machine in Fig. 8 is illustrative, rather than restrictive, as obvious the particular form of flying machine does not per se limit the application of our invent-ion.

As previously ointed out it is proposed to provide a com ination of parts whereby the flying machine will rise, with its burden, vertically in its ascent and descend to the earth vertically and landing thereon without a shock of importance enough to notice, the aforesaid actions operating somewhat in the nature of an auger entering wood.

To this end we propose to provide a plurality of compressors orcondensers 14, each having an open front and rear, as shown, a flat bottom 15, sides 16 and a top portion 17. Upon inspection of Figs. 1 and 2, it will be observed that the sides 16 converge from the forward edge to .the retreating edge of the condenser, and further that the top portion 17 slopes downwardly from the forward edge to the retreating edge, this arrangement producing a structure wherein the width and length of the forward edge is greater than the retreating edge as to Width and length. In short, each condenser presents an open front of a greater area'than its open rear. As shown in Fig. 2, we provide four of these condensers, though, of course, no restriction as to number is contemplated, and between each pair of condensers we position a plurality of blades which are inclined at an acute angle to the horizontal plane of said condensers, the leading edge of the bladesbeing adjacent the retreating edge of said condensers.

The means for carrying said condensers 14 and blades 18 comprises the element 19, shown in Figs. 3 and 4, and embodies a plurality'of outwardly directed flanges 20, to each of which a condenser is secured by means of fasteners 21, (see Fig. 2). Said element 19 is further provided with spaced lugs 22 for the reception of the end portions 23 of said. blades,'suitable fasteners 24 being used for this purpose, as clearly shown in said Fig. 2. As shown in Fig. 1, the bore 25, in said element 19, receives a sleeve 26, the latter fitting around shaft 27, the latter, the sleeve 26 and the element 19 being bound together by means of a pin 28, or the like. The lower portion of said shaft 27 is reduced in diameter, as shown at 29, for the reception of a coupling 30 and a base member 31, the latter being suitably affixed to the fuselage 13 of a flying machine. As' shown in Fig. 1, the end of the shaft portion 29 carries a bevel gear 32 meshing with a similar gear 33, af-

fixed to shaft 34 extending from any con-.

venient source of power, (not shown). Obviously, the rotation of said shaft 27 and the parts carried thereby, is imparted from said shaft 34, and in order to reduce friction to a minimum we propose to provide a thrust collar -,35 ,which is interposed between the fuselage 13 and the gear 32, and further it will be noted upon inspection of Figs. 5 and 6, that said base member 31 is provided'with a ball race 36 which cooperates with a ball race 37 in said coupling 30 to define a continuous groove for the reception of ball bearings 38, Said coupling 30 is afixed to the shaft portion 29, by means of screws 39, or the like, and naturally rotates with the shaft together with the parts just described.

As shown in Fig. 1, said sleeve 26 also supports a propeller arrangement 40, which includes a suitable casting 41, having a knob portion 42 at one end and a threaded stud 43 at its other end, the latter being provided with left-hand threads and adapted to threadedly engage the upper portion of said sleeve 26 as shown. In view-of this arrangement it is obvious that the propeller 4O rotates with the shaft 27.

After the flying machine has been equipped with our invention and it is deslred to ascend, the usual motor, with which the machine is equipped, is started, the power being transmitted to the shaft 27 and its connected parts, through the bevel gearing 32-33 and shaft 34, all parts rotating simultaneously;

supplied a continuous solid air force, the 'machine rises upwardly. Hence the chief lifting power is to be considered primarily as present in the plane and secondly, by the converging top portion of said condensers. Obviously, as the speed of rotation of the condensers increases a like increase takes place in the velocity of air passing through said condensers. When the machine descends under the law of gravitation, its drop is retarded by regulating the rotation of the condensers, which will permit said machine to descend so graddally and lightly as not to cause a single shock to its occupants.

An inspection of Fig. 7 will instantly reveal the actions hereinbefore described in detail. It will also become apparent that the converging or sloping top portions of the condensers have a certain hfting power in themselves as they cut through the air in operation'and olfer but a very little resistance to the'air when in operation. As the length and width at the leading'edge of the condensers is greater than the length and width at the retreating or rear edge, it follows the aforesaid convergence, air currents of great force leave the retreating edge of the condensers and impact the blades 18 which are pitched at an angle to cause a lifting action in-said machine.

As shown in Figs. 9 and 10, the condensers 14 may be made box-like in formation, hinged vanes 44 being internallyv arranged adjacent the sides of said condensers as shown. These vanes may be swung outwardly to the positions, indicated and locked in that position by means of pins 45 arranged in one of the apertures 46. This arrangement permits a certain amount of adjustment to regulate the quantity of air. passing through the .condensers. In this instance, and in our preferred form, the condensers rotate in the direction of the. full-line arrows, while the discharged air moves in the direction of the dot-and-das h arrows.

,While the present is a disclosure of the like compressors having a forward edge of preferred embodiments of the invention, it

is to be understood that the same is not limited .thereto, as various changes in the minor details of construction, proportion and arrangement of parts may be resorted to without departing from the spirit of the invention as defined in the appended claims.
